TOPIC: Items and value from another db

Items and value from another db 10 years 1 week ago #31863

Hi,
I have 3 db in my localhost server (db1:joomla, db2:my stats, db3:other db).
Rsform working on db1.
Can I take results from db2?

The host is the same; user db and pwd db is the same.
Normally I write in the default value my code:
//<code>
$db =JFactory::getDBO();
....
...
return $ result;
//</code>


How can i do with another database in the same server?

Thanks!

Accessing tables that are in the same database as the Joomla! installation is done through this method:
$db = JFactory::getDbo();

However, if you are trying to connect to an external database, you will need a different approach. Basically, you will need to use
JDatabaseDriver->getInstance
as per this example:
 
// create an empty array to hold the options
$option = array(); 
 
// build the method's paramaters here:
 
$option['driver']   = 'mysql';            // Database driver name
$option['host']     = 'db.myhost.com';    // Database host name
$option['user']     = 'fredbloggs';       // User for database authentication
$option['password'] = 's9(39s£h[%dkFd';   // Password for database authentication
$option['database'] = 'bigdatabase';      // Database name
$option['prefix']   = 'abc_';             // Database prefix (may be empty)
 
$db = JDatabaseDriver::getInstance( $option );
 

Straight from the Joomla! docs:

https://docs.joomla.org/Connecting_to_an_external_database

PS: this would require moderate scripting knowledge

Can anybody help to find the solution.
Thanks.
$option = array(); //prevent problems
 
$option['driver']   = 'mysql';            // Database driver name
$option['host']     = 'localhost';    // Database host name
$option['user']     = 'user';       // User for database authentication
$option['password'] = '';   // Password for database authentication
$option['database'] = 'crm_db';      // Database name
$option['prefix']   = '';             // Database prefix (may be empty)
 
$db = JDatabaseDriver::getInstance( $option );
 
{
$db->setQuery('SELECT MAX acc_id FROM crm_accounts');
$nr_acc = $db->loadResult();
}
 
return $nr_acc;
$_POST['form']['nr_acc'] = $nr_acc;
